The Aston Martin DBR1 is a sports racing car built by Aston Martin starting in 1956, intended for the World Sportscar Championship as well as non-championship sportscar races at the time. It is most famous as the victor of the 1959 24 Hours of Le Mans, Aston Martin's only outright victory at the endurance classic. It is one of only three cars in the 1950s to win both the World Sports Car Championship and Le Mans 24 Hours in the same year. In addition the six World Sports Car Championship victories was a record for any car in the 1950s and remained a record in the championship until surpassed by the Ferrari 250TR. The three consecutive triumphs in 1959 at the Nürburgring, Le Mans and the Tourist Trophy equalled the record set by the Ferrari 250TR with its three consecutive victories at the start of the 1958 season.
